5. Avoid cocktails: It is a bad idea to mix chemicals trying to formulate a magic concoction. Other chemicals can affect the effectiveness of others. Iodine is one example of a disinfectant that can be inactivated relatively easily. Secondly, this is not safe. Remember baking soda and vinegar from science class?
6. Cost. Do not make the mistake of simply comparing the cost per ounce of the concentrated product. Take into consideration mixing directions and estimated coverage area to compare the cost of disinfection per square foot. The thumb rule is that 1 gallon will cover about 100 square feet. Now, how many square feet are in a calf hutch again?
I have only touched the tip of the cow patty on this topic. To really educate yourself and find some handy charts on selecting disinfectants, read veterinarian Glenda Dvorak’s paper at: http://tinyurl.com/yboe7wn.
